CARBURETER.

. Specification of Letters Patent.

Application filed June 18, 1914. Serial no. 845,830.

- To all whom it may concern cation.

My invention relates to carbureters employed in the generation of carbureted air from gasolene or other combustible fluids or fuels and hasfor its object the production of a simple, durable and efiioient apparatus arranged to vaporize combustible fluids to be combined with free air.

, More particularly my invention consists in a carburetor having air and mixing chambers connected by a valve or means for injecting the combustible fluid.

To this end and purpose my invention consists in the novel construction, provision, comblnatlon, associatlon and relatlve pos1- tion of parts and members set forth in the following specification and accompanying drawings and more particularly brought out in the claim..

Referring to the drawings in which like reference characters indicate like or corresponding parts, Figure 1 is a cross section of mypreferred form of construction. Fig. 2 is a part section showing a side view of the rack and pinion for operating the valve. Fig. 3 is a sectional plan taken on line 33 of Fig. 1, showing the valve in full open position and Fig. 4 is a sectional plan taken on the same line 33 of Fig. 1 but showing the valve in closed position. v

Referring to the illustrations, the air supply chamber 1 is provided with a fuel container or trough 2 which is threaded'at 2" to receive the mixing chamber 3. Within the inner periphery of the container 2 is a valve 4 provided with a plurality of converging passages 4 which have small openings 4 into the passage 4 which connects the air and mixing chambers, and enlarged openings 4 communicating with the container discharge openings 2 As shown in Figs. 1 and 2 a rack 5 and pinion 6 which is operated by means of rod 6 and arm 6", rotate the valve 4 to open and close the discharge openings 2", as illus-- trated by Figs. 3 and 4. The supply of the combustible fluid through pipe 7 into the container 2 is controlled by a valve 8.

ree air is forced into the air chamber 1 by means of a fan 9 or itsequivalent and passes through the opening 4 where it combines with the atomized combustible fluid and to facilitate the thorough mixingof both vaporized fluid and air, a mixing fan 10 is provided which operates by means of the shaft 11 having a bevel gear connection 12 and 13 with the fan shaft 14. A plurality of brackets 15, 15 and 15 support the shafts 11 and 14. The fan shaft 14 is operatively connected to the engine shaft so that the supply of air to the carbureter is increased or decreased 'with the speed of the engine.

In operation, the valve 8 is 'opened by means of rod 16 and arm 16 and the combustible fluid enters the trough or container 2 and is retained thereuntil the valve 4, operated by the rack 5 and pinion 6, is moved from the closed position shown in Fig. 4 to the open position of Fig. 3. This allows the fuel to enter the passage 4 through 2 and 4 The fan 9, or its equivalent, which is operatively connected to the engine by means of shaft 14, forces air into the air chamber 1 and through the passage 4 where it combines with fuel drawn from openings 4", and

passes on into the .mixing chamber 3, where it is thoroughly mixed by the fan 10 which is operatively connected to shaft 14 by means of the gears 12 and 13.

Having thus described my invention it is obvious that various immaterial modifications and changes may be made without departing from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact form, or construction as illustrated.

I claim as my invention: 2

A carbureter having a valve chamber and a mixing chamber, a rotating valve member in such valve chamber, such valve having a restricted air inlet opening through its center communicating with such mixing'chamber and converging radial passages opening into such restricted opening, a fuel receptacle having openings communicating with such converging passages, a shaft extending through such restricted air inlet opening,

through the valve member, a mixing fan in ,scribed iny name in the presence of two wit the mixing chamber fixed to such shaft, an-

other fan adapted to blow air through suchresti'ictod air inlet opening, means rotati ve'l connectmg such second fan with such sha and means for drlvmg such second fan.

In witnesswhereof, I have hereunto subn'esses this 15th day of June, 1914. 5 JOHNWEIOHWALD.
